SMSL Audio G1 Master Clock

Rediscover True Musical Timing
The SMSL G1 is SMSL’s first external master clock, designed to eliminate jitter and distortion at the source of digital audio. By synchronizing CD players, media players, and DACs, the G1 ensures every note is delivered with precision and clarity, restoring the natural soundstage and detail of music.

Why Do You Need a Master Clock
In digital audio, every beat is defined by the clock. Even nanosecond-level jitter can cause sound distortion, blurry low frequencies, and reduced soundstage. The G1 provides professional studio-grade timing accuracy, creating a unified time base across your entire system.

Precise and Stable Crystal Oscillator
The G1 uses an SC-Cut OCXO oscillator with ultra-low phase noise. At 1 Hz, phase noise is just -105 dBc/Hz, 35 to 50 dBc lower than femtosecond clocks. With a frequency accuracy of ±3 ppb, it would take 10 years of operation to deviate by only one second.

Constant-Temperature Protective Chamber
To ensure the crystal oscillator performs in the purest environment, the G1 uses a custom constant-temperature shielded chamber. After multiple rounds of testing, this dual-layer design provides thermal insulation and stability, eliminating micro temperature fluctuations for consistent clock performance.

Multi-Channel Drive Design
The G1 features a quad-channel output design, with each channel independently buffered. This ensures strong driving ability, stable impedance, and precise synchronization across multiple devices, delivering signal integrity without loss.

Compact and Meticulous Design
Despite its advanced internal technology, the G1 features a minimalist CNC-milled aluminum chassis. Its compact footprint fits easily into any system, while its design ensures durability, heat dissipation, and low EMI interference.

System Pairing and Applications
The SMSL G1 achieves its full potential when paired with SMSL’s flagship components such as the T2 CD Transport, D2R DAC, and P2 headphone amplifier. By synchronizing timing across the chain, the G1 ensures accurate signal transmission, detailed soundstage, and smooth dynamic performance, unlocking the full potential of high-end audio systems.

Power Supply Design
Equipped with an imported toroidal transformer linear power supply, the G1 features automatic voltage switching, triple regulation, and multi-stage suppression. Combined with CNC casing heat dissipation and supercapacitors, it provides an ultra-clean 6 μV-level power environment for optimal OCXO and circuit performance.
